Bug ID: 508263
Summary: Task Manager not grouping processes together
automatically (LibreOffice processes don't group
together on the taskbar if opened via "Open"
button/shortcut)
Classification: Plasma
Product: plasmashell
Version First 6.3.6
Reported In:
Platform: Debian stable
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Task Manager and Icons-Only Task Manager widgets

Target Milestone: 1.0

Video showing the bug, as well as showing that closing a program forces the
task manager to refresh and group the windows.
SUMMARY
The task manager is not grouping LibreOffice applications together instantly
when one opens files in the same LibreOffice application if they were opened
via the Open option (File -> Open, or CTRL + O), creating two ungrouped icons
of the same type of LibreOffice window on the taskbar; for example, 2
windows/icons of the process libreoffice-calc are displayed, instead of having
both windows grouped under the same icon. It appears that opening the second
file in LibreOffice doesn't cause the taskbar to refresh as expected. One needs
to force the task manager to refresh to get the windows in the task manager to
group together, which can be done by opening or closing another unrelated app
or opening the task manager settings (among other ways). This bug affects both
the Icons-Only and Icons-and-Text Task Managers on Wayland only.
STEPS TO REPRODUCE
1. Ensure one's taskbar is using the Icons-Only Task Manager. Ensure that
grouping is enabled (Under Behavior -> Group, select "by program name").
2. Open a new LibreOffice Calc window in a Wayland session from either the
Applications menu or a pinned icon on the taskbar.
3. Open any file that opens in Calc (via CTRL + O or File -> Open). Note that
the file must not be blank inside.
4. Using LibreOffice's "Open" option (CTRL + O or File -> Open), open a second,
different file that opens in LibreOffice Calc. Note that the file must not be
blank inside.
OBSERVED RESULT
The 2 LibreOffice Calc processes on the taskbar are ungrouped until one forces
the task manager to refresh with another action.
EXPECTED RESULT
The 2 LibreOffice Calc processes on the taskbar should be grouped together
immediately after the second file is opened.

ADDITIONAL INFORMATION
Calc was used for demonstration purposes, but the same bug affects the other
LibreOffice programs (Writer, etc).
My guess is this bug is happening because LibreOffice opens an soffice.bin
process of some type when a document is opened via CTRL + O that turns into the
type of process being used (example: if using a calc file, it opens as
soffice.bin which quickly turns into a libreoffice-calc window). The task
manager may be refreshing too quickly to realize that there are now two active
libreoffice-calc windows open; it's only looking at the initial soffice.bin
process and separating it on the task manager, but doesn't realize that the
process renamed itself afterwards and should now be combined until a refresh
tells it to do so.
Opening the second file in step 4 via a file manager (Dolphin, etc) also causes
the bug.
One can work around this in step 4 above by opening a brand new document
(CTRL+N/File -> New -> Spreadsheet) instead of an existing document and then
opening the desired document as normal in that new window (I believe this works
because it skips running the file as an soffice.bin process first and goes
directly to being a libreoffice-calc process). One can also work around this by
opening or closing any other app or going into the task manager's settings,
which seems to force a refresh of the task manager and makes the icons group
together.
I've tried both the Flatpak and native versions of LibreOffice; the same bug
happens with both.
